Std Bank's Bad Call centre for vehicle finance.

I assisted my son to apply for online vehicle finance yesterday. We both tried to call the Tel. No: *** that we were given to call. He couldn't get through and when I called, and the recording tells a person that they have high call volumes but just hold on, as your call will be answered by the next agent. After 25 minutes I had to hang up as I get phone calls for my business as well, which I answer. We'll have to go to Wesbank instead as this is pathetic to waste a persons time like this. I thought your service is better than that Std. Bank. Why not have the option to leave a message to be called back?
